Energy extraction technology usage


To gain a sense of the relative scale of the proportions to world energy usage, the following treemap shows the proportions of world energy used in 2005 according to its “source”. The total area of the diagram represents the entire usage of that year, and the area of each of the subrectangles is proportional to its contribution.
